JOURNAL-BOX.

- Application filed May 16, 1913.

T 0 all whom it may concern Be it known that I, DONALD G. DAVIS, acitizen of the United States, residing at Depew, in the county of Erieand State of New York,- have invented a new and useful Improvement inJournaLBoxes, of which the following is a specification.

This invention relates to car journal boxes and particularly to animproved construction of means for operating the lid of a. box andholding the same closed. In journal boxes for car axles it is necessaryto provide lids to close the boxes so as to prevent the entry ofcinders, dirt and water thereinto,

and in order to maintain the lids in close en-- gagement with the endsof the boxes so as to enable them to properly perform the desiredfunction and also to prevent rattling,

- springs are commonly employed.

The "present invention provides an improved construction whereby acoiled or helical spring, possessing a greater degree of resilience thanthe flat springs usually applied to journal box lids, may be employed onthe inside of the lid. The use of such coiled springs involves theprovision of a forwardly projecting block or abutment attached to thetop of the journal box and the present invention provides an improvedconstruction for this abutment, whereby the same may be detached fromthe journal box so as to permit the application to the box of a standardM. G. B.v lid if desired.

The present invention also contemplates an improved bearing for thelower end of the helical spring and certain other features ofimprovement, the nature of which will appear from the following detaileddescription.

In the accompanying drawings: Figure 1 is a front elevation of a journalbox and lid embodying one form of the invention, a portion of the lidbeing broken away. Fig. 2 is a vertical central section through thefront part of the journal box and lid, the position of the lid when openbeing shown Fig. 3 is a fragmentary sectional view on line-3'-3, Fig. 2,on an enlarged scale. Fig. 4 is a fragmentary sectional view on line 4%,Fig.' 2, on an enlarged scale. F'g. 5 is a view similar to Fi g. 1,showing modified construction. Fig. 6 is a vertical central sectionalview through the front end of the journal box and the lid shown in Fig.5,. Fig. 7 isa detail sectional Specification of Letters Patent.

view on line 77, Fig. 6. Fig. 8 is a fragmentary vertical sectional Viewof another modified construction.

Referring particularly to Figs. 1 to l, 1 designates a journal box whichmay be of any usual or well known construction. This box has an openfront which is adapted to be covered by a lid 2. At the top of the boxare a pair of perforated lugs 3 connected by a web 4. The lid 2 isprovided with pintle bearings 5 and with a hood or pocket 6 adapted toextend up over the lugs on the top of the journal box and also toreceive the lid operating spring and its associated parts. The lid ispivoted to the ournal box by means of a pintle 7 extending through thebearings 5 and holes in the lugs 3. The web 4 preferably has asubstantially vertical flat front face 8 and a flat top face 9 disposedat an angle to said front face, the formation. of these parts being suchas to adapt them to cooperate with the Well known fiat spring of theordinary M. C. B. lid so as to hold such a lid in open or closedposition upon the box in a well understood manner. vention, however,instead of the lid '2 being provided with a fiat spring as in the M. C.B. lid. a coiled or helical spring 10 is used. This spring is mountedupon aguide rod 11 having a pivotal engagement at its upper end with ablock 12 secured to the web 4. The pivotal connection between this rodand the block may, be of any suitable nature but preferably the-block isprovided with two arms 13 connected by a transverse pivot pin 14, andthe rod 11 is provided with a forked upper end or head 15 adapted toengage this pivot pin between the arms 13. The upper end of'the spring10 engages the lower face of the head 15. The lower end of the spring 10is caused to act upon the lid 2 in any suitable manner. In the preferredconstruction illustrated, the lid 2 is provided with a pair of inwardlyprojecting lugs 16 in which. are slots 17 An abutment or guide block 18is supported by these lugs by means of trunnions 19 projecting intotheslots 17. The block 18 has an aperture 20 therein through which thelower end of the rod 11. passes and is guided. The lower end of thespring 10 rests upon the upper face of the block or abutment 18.

The block 12, which is separate from the journalbox, may be secured tothe Web 4 In accordance with the present inand lugs 3 at the top of thejournal box in any suitable manner.

In theconstruction shown in Figs. 1 to 4, the block 12 has ascrewthreaded socket therein into which screws the threaded end of aneye-bolt 21. The head of this eye-bolt seats in a recess 22 formed inthe rear face of the web 4, while the pintle 7 passes through the eye ofthe, bolt. The pintle is preferably provided with a portion 23 ofreduced diameter adapted to be engaged by the wall of the eye in thebolt head when the bolt is tightened upon the eye-bolt, thus serving tohold the pintle against longitudinal displacement. 'With a pintle ofthis construction it is unnecessary tov use any other locking means,such as the customary cotter pin, nor need the pintle be provided with ahead. The eye bolt is held against rotation by its engagement with thewalls of.

the recess 22 and by the passage through its eye of the pintle while theblock 12 is prevented from unscrewing from the bolt by the engagementwith it of the head of the guide-rod 11. l i The apparatus abovedescribed is assembled by placing the lid in position and pass ing thepintle through the bearings 5, holes in the lugs 3, and the eye of thebolt .21 which is loosely placed in itssocket. The lid is then lifted tothe position shown in dotted lines in F ig. 2, when the block 12 can bereadily screwed upon the .threaded part of the eye-b olt. The block isscrewed up until it engages firmly against the front face of the web 4and draws the eye-bolt into its seat and into engagement with theportion of the pintle of reduced diameter.

This locks the pintle, eye-bolt and block firmly in position. The blockor abutment 18 is then placed in position between the lugs 16, thetrunnions 19 being readily engaged with the slots 17 by inclining theblocks to the plane of the lid. The spring 10 is then placed upon therod 11 and the lower end of the latter is passed through theopening inthe block 18. The rod- 11 is then forced in the direction of the block18 and the spring 10 is compressed sufliciently to permit the forkedhead 15 of the rod-to be engaged with the pivot 14 carried by the block12. The rod is then released and the spring 10 holds the forked head infirm engagement with'the pivot pin. The spring being still under somecompression holds the lid in the open position shown in dotted lines inFig. 2. As the lid is forced down, the line or reaction of the springpasses from one side of the pivotal axis of the lid to the other sothat'when the lid is'closed the spring holds the same'firmly against theend of the journal box, thus securing the desired tight'joint and holding the lid firmly against rattling.

The parts may be disassembled as readily maybe attached thereto in the.usualmanner.

In the modification shown in Figs. 5, 6

and 7, the journal box 1, lugs 3 and lid 2 are of the same constructionas that described. The lid 2 is pivoted to the lugs, however, by meansof the ordinary pintle 80 providedwith a head 31 and held in position bya cotter pin 32. The block 33 to which the spring guide rod is pivotedis provided with a rearwardly projecting lug web 4 connecting the lugs 3and is provided with an aperture or eye 36 through which the pintle 30passes. The pintle in this way holds the block 33 in position. The blockis provided with the forwardly projecting arms 37 between which ispivoted, by means of a pivot 38, the head 39- of the spring guide rod40. The lower end of the latter slides in a sleeve 41, having laterallyprojecting trunnions 12 which are received in the slots 17 in the lugs16 of the lid. The spring 10 fits over an enlarged portion of the guiderod, its upper end engaging moving thecotter pin 32 and the pintle 30the lid and block may be removed anda standard M. C. B. lid attached tothe boxby the pintle 30.

Fig. 8 shows a modified construction embodying some of the features ofeach of the two constructions above described. The box 1 and-lid 2 areof the form already described. The lid 2 is pivoted to the lugs on thebox by a pintle 30 which also holds in position a block 33' as describedin connection with Figs.- 5, 6 and 7. The block 33 has the forwardlyprojecting arms 37 connected by the pivot pin 38, which is engaged by aforked head 39 on the guide rod -10 similar to that on the guide shownin Figs 1 to 4. The guide rod, however, instead of engaging the sleevell is made long enough to pass through the central aper ture in a block18, such as described in connection with Figs. 1 to =1. The spring 10 ismounted on this guide rod and abuts against the head 39 and the block 18at its respective ends. Other modifications than those illustrated mayobviously be made in the invention.

In each of the constructions described the block for the pivotalconnection of the upper end of the spring guide rod consists of aseparate piece secured to the upper por- 3 which .fpasses through anotch 35 in the tion of the journal box. A block of this sort can bereadily forged or cast and if broken can be replaced at small expense,in addition to the fact that it can be detached to permit the use on thebox of an' M. C. B. lid.
